1 Corinthians 15:42
42 So also is the resurrection of the dead. It is sown a perishable body, it is raised an imperishable body;
I came across this this morning. This verse even by itself contradicts some people's belief that man will not spend eternity in the lake of fire, but instead "die forever". So it stands to reason that if God raises "imperishable" bodies, then obviously just as those who are with Him their bodies will not perish, but also those who are thrown into the lake of fire, the second death, will not perish.
Just wanted to share.
